David Hasselhoff has revealed his girlfriend keeps refusing to marry him. The former ‘Baywatch’ star has got down on one knee and proposed to Hayley Roberts, 31, twice in the past few days, and has now asked fans to help convince her to change her mind. The 59 year old posted a picture on his Twitter page of himself asking Hayley to be his wife in Cape Town, South Africa, where they are on holiday, with the caption, ‘I tried to pop the question but she was having none of it.’ He later updated with, ‘I popped the question in the dressing room. She’s still having none of it!’
